Abstract (en)
A process for separating a first gas, for example CO 2 , from a feed gas mixture comprising the first gas and a second gas, for example H 2 , in five or more adsorption beds each containing an adsorbent selective for the first gas. The process comprises subjecting each of the adsorption beds to a repetitive cycle comprising, in sequence, (a) a feed step, (b) a rinse step, (c) a pressure decreasing equalization step, (d) a blowdown step, (e) an evacuation step, (f) a pressure increasing equalization step, and (g) a repressurization step. The feed gas mixture may be a reformate from a steam-hydrocarbon reforming process.
